Bowman’s capsule – cup-formed sack lined by a simple squamous epithelium (parietal surface area) and specialised cells known as podocytes (visceral area) that take part in the filtration method; gets the filtrate which then passes on into the PCTs.

bursa – connective tissue sac containing lubricating fluid that stops friction concerning adjacent buildings, which include pores and skin and bone, tendons and bone, or between muscles.

basal nuclei – nuclei of your cerebrum (by using a several components within the higher brain stem and diencephalon) that are accountable for assessing cortical movement instructions and comparing them with the general condition of the person through broad modulatory action of dopamine neurons; mostly linked to motor capabilities, as evidenced with the signs and symptoms of Parkinson’s and Huntington’s diseases.

acute mountain sickness (AMS) – ailment that occurs a results of acute exposure to substantial altitude as a result of a lower partial strain of oxygen.
